DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fragrance cosmetic containing an ethanol solvent.

[0002]

2. Description of the Related Art In recent years, the necessity of care for body odor and the like has increased in accordance with changes in lifestyle such as the westernization of meals in Japan, and the demand for cosmetics for fragrance such as perfume and cologne has been increasing. .

[0003] In Japan, strong and fancy fragrances such as those found in fragrance cosmetics in Europe and the United States are less preferred due to their cultural background, but rather pale gentle fragrances are preferred. However, such fragrances have a problem in sustainability (persistence) due to the essence of being light and gentle.

[0004] Therefore, in order to improve the persistence of the scent, conventionally, a large amount of a scent having a retaining action of musk or the like is used, a scent is added to micelles obtained by emulsifying cosmetic ingredients, or β- Methods such as controlling the release of fragrance by including a fragrance in cyclodextrin and the like have been proposed.However, in the above method, the fragrance such as musk has an animal odor that itself has, so the fragrance is heavy. The method involves a qualitative change, such as causing the cosmetics to become sticky due to the emulsifiers and fats and oils used in the emulsification method. However, there is a drawback that the fragrance changes remarkably with time, and none of these methods is sufficient.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fragrance cosmetic composition which has a good feel and which can greatly improve the scent persistence without a qualitative change of the scent. .

[0006]

Means and Action for Solving the Problems In view of the above-mentioned situation in the prior art, the present inventors have conducted intensive studies and found that methacrylic acid ester resin powder is blended with a fragrance cosmetic containing ethanol. In addition, the present inventors have found that not only the feel but also the scent persistence is significantly improved without qualitative change of the scent.

That is, the cosmetic for fragrance of the present invention comprises 0.1 to 10% by weight of methacrylate resin powder, 1 to 20% by weight of fragrance, 1 to 70% by weight of ethanol, and preferably 5 to 70% by weight of water. And the blending amount of the fragrance is larger than the blending amount of the methacrylic acid ester resin powder.

Hereinafter, the cosmetic for fragrance of the present invention will be described in detail. The methacrylic acid ester resin powder used in the fragrance cosmetic of the present invention is prepared by subjecting at least one methacrylic acid ester monomer to a usual method,
For example, radical polymerization may be performed in the presence of a polymerization initiator such as benzoyl peroxide, and the resulting polymer or copolymer may be pulverized by a pulverizer or the like, or at least one of methacrylic acid ester monomers may be used. Emulsion polymerization of the seeds as fine emulsified particles, after removing the solvent, may be produced by drying the resulting spherical hollow polymer or copolymer particles as they are,
A spherical hollow powder obtained by the latter emulsion polymerization is preferred.

Examples of the ester group of the methacrylic acid ester include ethylene glycol, methyl, ethyl and the like, but are not particularly limited as long as the obtained polymer or copolymer is not deteriorated by other components such as fragrance and ethanol. .

The particle size of the methacrylate resin powder obtained as described above is 100 μm or less, particularly 10 μm.
The following is preferred. This is because the larger the particle size, the easier it is to settle and become a cake, and the more difficult it is to re-disperse when shaken.

The amount of such a methacrylate resin powder is suitably in the range of 0.1 to 10% (% by weight, hereinafter the same). This is because if the amount is less than 0.1%, the scent retaining effect is impaired, and if it exceeds 10%, the feeling of use is impaired by the powder.

Next, all known fragrances for fragrance can be used. The compounding amount is suitably in the range of 1 to 20%. This is because if the fragrance is less than 1%, the fragrance is weakened, so that it is not suitable for fragrances. If it exceeds 20%, the fragrance is too strong and also unsuitable for fragrances.

Further, in the present invention, ethanol is mainly used as a solvent for the fragrance. The compounding amount is suitably in the range of 1 to 70%, preferably 5 to 70%. This is because when ethanol is less than 1%, the refreshing feeling on the touch is impaired, and
If it exceeds 0%, the volatility is too high, so that ethanol is immediately evaporated from the adhering portion, and the powder hardens white.

The fragrance cosmetic of the present invention includes, in addition to the above resin powder, flavor and ethanol, optional components used in ordinary cosmetics, such as surfactants, as long as the effects of the present invention are not impaired. Preservatives, antioxidants, powders, humectants, alcohols, thickeners and the like.
